X2/Mini Lathe Controller adjust How-to ?

[olduhfguy]

I have just finished repairing a controller board for an X2 and I'm looking for adjustment procedures for the overload and speed control circuitry. I have the prints for the boards but no adjustment info. I have a feel for what the speed control pots do from looking at the scope and listening to the motor but there has to be a proper way to check these. I had to replace both op-amps on the daughter board so I'm sure things are off a bit, thanks !

Try this - maybe different board but may give clues? Pages 8 and 9 most relevant!

It's interesting reading - I'm beginning to think Sieg never released adjustment data for their boards. I think a little common sense listening to the machine motor may be the best way to adjust the torque and overload adjustments.
